constructed ina manner to properly cooperate with the electro-magnets 85 and 35 As the carriers reach their extreme inner positions, as illustrated in Fig. 2, the switch member 38 will have reached a position in which one of the circuits 36 or 36 isclosed; in the illustration in Fig. 2, the circuit 36 is -ly are in magnetic engagement with the shuttle 33 and accordingly attract and hold'the continues, the shuttle will be drawn towardthe left in Fig. 2, bytheaction of the carrier 17and the coupling connection between said shuttle and the electromagnets 35, this connection is maintained until the carriers are back again in their extreme inner positions whereupon the switch member 38 will have reached the position in which the circuit 36 is closed, the circuit 36 at the same time being broken. The electromagnets 35* now become energized and consequently are in magnetic connection with the shuttle 33, which as a result is drawn toward the right as the carriers 17 and 17 again move toward their extreme outer positions. This energizing and deenergizing of the electromagnets 35 and 35 in alternate sequence and the consequent connection with and disconnection of the shuttle in corresponding alternate sequence continues throughout any given period of operation of the loom.

In the form illustrative in Figs. 1' and 2, a positive connection is maintained between the shuttle and the actuating mechanism, through the entire operative paths of said shuttle. That is to say, throughout half of agiven path in one direction and a half of a given path in the return direction, the shuttle is in positive connection with one carrier and throughout the other half of said paths, is in positive connection With the other carrier. The shuttle is thus positively controlled throughout its entire range of movement and consequently is uniformly moved and is free from undesirable variations in speed and at the same time is positively maintained in its intended paths.

The loom as usualincludes harness mechanism operating in a manner to provide the shed of warp threads through which the shuttle is'passed by the mechanism illustrated and described and to reverse the,

threads in said shed in the well known way. In addition the loom may include all instrumentalities customarily found in looms and operating in proper sequence to perform their various functions.

Various changes in the specific form shown and described may be made within the scope of the claimswithout departing from the spirit of-my invention.

v I claim:

1. A shuttle shifting and carrying mechanism for looms comprising a pair of longitudinally movable carriers, means for inversely reciprocating the carriers in a transverse manner, a pair of'fingers carried by each carrier the fingers of one carrier being disposed in a plane different from that in which the fingers of the other carrier are located, a shuttle guiding'means upon said shuttle adapted to receive the fingers of each of the carriers simultaneously, and electromagnetic devices on said carriers for coupling the shuttle thereto, and switching means whereby said electro-magnetic devices are energized and tile-energized in alternate sequence to disconnect one carrier from and;

connect the other with, said shuttle and vice versa. I

2. A shuttle shifting and carrying mecha-nism for looms comprising a pair of longitudinally movable carriers, means for inversely reciprocating the carriers in transverse manner, a pair of fingers carried by each carrier, the fingers of one carrier being disposed in a plane different from that in which the fingers of the other carrier are located and arranged to overlap in the innermost position of the carriers, a shuttle guiding means upon said shuttle adapted to receive the fingers of each of the carriers simultaneously, and electromagnetic devices on said carriers for coupling the shuttle thereto, and switching means whereby said electroanagnetic devices are energized and ole-energized in alternate sequence to disconnect one carrier from and my hand.
